A pattern for building personal knowledge bases using LLMs.

This is an idea file, it is designed to be copy pasted to your own LLM Agent (e.g. OpenAI Codex, Claude Code, OpenCode / Pi, or etc.). Its goal is to communicate the high level idea, but your agent will build out the specifics in collaboration with you.

Most people's experience with LLMs and documents looks like RAG: you upload a collection of files, the LLM retrieves relevant chunks at query time, and generates an answer. This works, but the LLM is rediscovering knowledge from scratch on every question. There's no accumulation. Ask a subtle question that requires synthesizing five documents, and the LLM has to find and piece together the relevant fragments every time. Nothing is built up. NotebookLM, ChatGPT file uploads, and most RAG systems work this way.

This is a question that comes up quite often by windows users, so thought we would share how we normally do it. The question is

Can you run a PostgreSQL server on your windows desktop/server box without having to install anything?

The answer is

Stealers observed in the DriveSurge campaign (Silent Push: ClickFix + fake update driveby attacks on thousands of compromised sites). Two stage macOS malware with dedicated arm64 (Apple Silicon) and x86_64 (Intel) builds, obfuscated bash loader → ~30MB Garble Obfuscated Go stealer. Steals 100+ crypto wallets, macOS Keychain, browser creds/cookies, SSH/GPG keys. Patches Atomic Wallet & Exodus Electron apps to intercept passwords. Shows fake Ledger Live / Trezor Suite "security update" dialogs to phish 24-word seed phrases. Persistence via LaunchAgent + ~/.persistenced.
